A 54-page manuscript co-written by Albert Einstein and Swiss engineer Michele Besso has sold at auction on Tuesday (Nov 23) for a record-breaking $13 million.
According to Christie's auction house, which hosted the sale, the manuscript has set a new record for the most expensive autographed scientific document ever sold. The identity of the buyer has not been revealed, though Christie's noted that the auction attracted the interest of buyers around the world.
The manuscript in question was written by Einstein and Besso between June 1913 and early 1914, when the pair tested equations that would ultimately become the foundation of Einstein's theory of relativity.
